Kinesiology Final Review

A physical therapist assistant positions a patient in supine prior to performing a manual muscle test of the supinator. To isolate the supinator and minimize the action of the biceps, the physical therapist assistant should position the patient’s elbow in:

• 30 degrees of elbow flexion

• 60 degrees of elbow flexion

• 90 degrees of elbow flexion

• terminal elbow extension

Which of the following describes the components of early swing phase?

• Occurs between 75%-85% of gait cycle

• the non-weight bearing leg begins to accelerate forward

• the non-weight bearing leg begins to decelerate in preparation for heel contact

• the ankle is plantarflexing from concentric contraction of gastrocnemius

Which of the following statements is (are) true regarding normal curvatures of the vertebral column?

• the cervical & lumbar regions are both normally lordotic

• the thoracic and lumbar regions are both normally kyphotic

• the cervical and sacral areas are both normally kyphotic

• the lumbar region is the only region of the spine that is normally lordotic

An anterior pelvic tilt is naturally accompanied by which of the following positions?

• increased lordosis of the lumbar spine

• decreased lordosis of the lumbar spine

• strong activation of the abdominals

• near maximal elongation of the hip flexors

Which of the following statements is true regarding abduction of the index finger?

• A. This motion occurs in the frontal plane

• B. This motion is described as the index finger moving away from the middle finger (towards thumb)

• C. This motion describes the index finger moving toward the middle finger

• A and B

• A and C

Which of the following statements is FALSE regarding the external oblique muscle?

• Activation of the right external oblique produces rotation to the left

• Activation of the right external oblique produces rotation to the right

• Bilateral activation of the external obliques can produce a posterior pelvic tilt

• Bilateral activation of the external obliques can produce trunk flexion

A patient diagnosed with shoulder pain of unknown etiology is referred by his physician for magnetic resonance imaging. Results of the test reveal a partial tear of the infraspinatus muscle. Which muscle group would be the MOST seriously affected by the injury?

• Shoulder external rotators

• Shoulder internal rotators

• Shoulder abductors

• Shoulder flexors

Injury to the musculocutaneous nerve will most likely result in:

• Elbow extensor weakness

• Elbow flexor weakness

• Pronator weakness

• Shoulder extensor weakness

During this phase of the gait cycle, the extended knee prepares to flex and the hip continues to extend, ending in about 10 degrees of extension (40% of gait cycle).

• Heel-off

• Foot-flat

• Toe-off

• Midstance

A closed-chain motion:

• Always provides larger ranges of motion than an open-chain motion

• Occurs when the distal segment of the joint moves relative to a stationary proximal segment

• Occurs when the proximal segment of a joint moves relative to a stationary distal segment

• Typically is not used when treating a patient
